Experience the difference: from aesthetic delights to critical functionality​

High CRI LED strip lights are designed to accurately and faithfully reproduce the colors of illuminated objects, ensuring a vivid and authentic visual experience. These LED strip lights are celebrated for their exemplary color reproduction and well-crafted spectral power distribution (SPD). High CRI LED strip lights reign across diverse applications by providing unparalleled color accuracy, adaptability, and efficiency. Their influence spans from aesthetic considerations in residential spaces to critical functionality in commercial, medical, and creative environments.

Light spectrum​

The primary strength of High CRI LED strip lights lies in their ability to accurately render colors across the visible spectrum. An LED strip light can be characterized as having a particular spectral power distribution (SPD), which can affect the color reproduction performance of the light emitted by the LED. SPD is a graphical representation of how the radiant power emitted by a light source is distributed across different wavelengths in the electromagnetic spectrum. The visible spectrum encompasses a range of colors, from violet to red. Each color corresponds to a specific wavelength of light. To deliver high color rendering, the LEDs of a strip light must emit a balanced amount of radiant power across all these different parts of the visible spectrum. This ensures that all colors are adequately represented without color biases or distortions.

LED technology​

Different LED technologies result in variations in the SPD. LEDs use phosphor conversion to generate visible white light. Blue-pump LEDs emit blue light in the range of approximately 450-480 nanometers. The blue light emitted stimulates a phosphor coating applied on the LED chip. The phosphor absorbs the blue light and undergoes a process called down-conversion, where it re-emits light at longer wavelengths. The combination of the original blue light and the re-emitted longer-wavelength light results in a broad spectrum of visible light, creating white light. Violet-pump LEDs emit light in the violet range, typically around 400-420 nanometers. Similar to blue-pump LEDs, violet-pump LEDs use a phosphor coating on the LED chip. The violet light stimulates the phosphor, which then re-emits light across the visible spectrum. The combination of the original violet light and the re-emitted longer-wavelength light results in white light.

The choice between blue-pump and violet-pump LEDs is influenced by specific applications and aesthetic preferences. Blue-pump LEDs are generally efficient and have high lumen output, but may have challenges in rendering red tones accurately, as they often lack certain wavelengths in the red part of the spectrum. The phosphor down-converter is instrumental in influencing the color rendering performance of blue-pump LEDs. Violet-pump LEDs have the potential to enhance the rendering of warm tones and red colors due to their emission spectrum extending into the longer wavelengths. The inclusion of shorter wavelengths in the violet range and longer wavelengths in the red range can contribute to a broader and more balanced spectrum of light. This can address the common challenge faced by blue-pump LEDs.

Color rendering metrics​

High color rendering LED strip lights typically have a CRI (Color Rendering Index) value of 95 or above, and an R9 value above 75. The R9 value, which specifically measures the accuracy of rendering saturated red colors, is provided as a separate and additional piece of information alongside the overall CRI score. This value is particularly relevant in applications where red hues play a significant role, ensuring that the LED strips deliver vibrant, true-to-life red tones for a variety of visual experiences and applications. The Technical Memorandum 30 (TM-30) is frequently employed alongside the CRI to provide a more comprehensive and nuanced evaluation of a light source's color rendering capabilities. It includes metrics such as the Fidelity Index (Rf) and Gamut Index (Rg), offering a more nuanced understanding of how a light source renders colors across the spectrum. TM-30 includes a specific metric (Rf,1) that assesses the rendering of skin tones. This is particularly relevant in applications such as retail, hospitality, and residential lighting where the accurate representation of skin tones is important. In television and film production, the Television Lighting Consistency Index (TLCI) is frequently evaluated to ensure that the colors rendered by an LED strip are suitable for capture by television and film camera sensors.

Types of high CRI LED strip lights​

The diverse types of high CRI LED strip lights, encompassing SMD, COB and neon, cater to various aesthetic, functional, and environmental requirements. SMD LED strips are a common and versatile type, featuring discrete LED packages mounted onto the printed circuit board. SMD LED strips are generally more flexible and compact compared to COB LED strips. The individual SMD LEDs are smaller, allowing for more flexibility in the design and application of the strip. This makes SMD LED strips suitable for installations where space is limited or where a compact form factor is desired. COB LED strips utilize a densely packed array of LED chips directly mounted onto the PCB. This makes them advantageous in applications where a higher level of brightness or intensity is required. COB LED strips provide a more uniform light output compared to SMD LED strips. This uniformity makes these LED strips suitable for applications where consistent illumination across a surface is critical. Neon LED strips, also known as LED neon flex or neon rope lights, replicate the appearance of traditional neon lights and provide uniform diffused light along the entire length. They are favored for applications where their unique characteristics, such as aesthetic appeal, diffused lighting, flexibility, and waterproof features, are essential for achieving the desired lighting effect.

Illuminating a world of color-critical applications​

High CRI LED strip lights offer a range of advantages that make them a preferred choice for applications where accurate and vibrant color reproduction is crucial.

In art galleries and museums, the exceptional color accuracy and quality of light produced by High CRI LED strips contribute to a heightened appreciation of the displayed art. Faithful color reproduction allows viewers to appreciate fine details, textures, and subtle contrasts in paintings, sculptures, and other exhibits as intended by the artists. Many High CRI LED strips are designed to emit minimal ultraviolet (UV) light, reducing the risk of UV damage to artworks.

In retail spaces, especially those showcasing clothing, cosmetics, or merchandise with vibrant colors, high CRI LED strip lights allow retailers to showcase merchandise with precision and to highlight the quality and details of various items. This helps customers make informed decisions based on the true appearance of products. The balanced light spectrum of high CRI LED strips helps enhance visual merchandising, making products more appealing to customers. The accurate and vibrant colors contribute to eye-catching displays that attract attention and drive sales.

The applications of high CRI LED strip lights in jewelry display lighting go beyond basic illumination. They ensure accurate and faithful color representation, allowing jewelry pieces to be showcased in their true colors. High CRI LED strips bring out the intricate details and craftsmanship of jewelry pieces. They contribute to a captivating and visually stunning presentation that attracts attention by enhancing the sparkle and brilliance of gemstones, diamonds, and other reflective surfaces. These LED strips serve as a key element in creating a visually captivating and premium showcase for precious jewelry, creating a luxurious and upscale ambiance in jewelry displays.
